1- Why does rendering use 2 percent of the CPU?
2- Why do video thumbnails disappear from the timeline?
3- Why does rendering continue intermittently? I'm having the same problems even when rendering a simple audio file. Why?
4- I bought all this equipment so I could do things quickly. What's wrong? What am I doing wrong?
5- Why not tell your source and rendering format exactly?
Please provide information as requested in https://www.vegascreativesoftware.info/us/forum/important-information-required-to-help-you--110457/
... especially which build of Vegas Pro 21 are you using? And what media are you using? - a MediaInfo report would be most helpful (the free app is linked to in C-1 in the above link).
Vegas Pro 21 has not been available to purchase from MAGIX for nearly one year - have your problems only appeared recently? If yes, has something changed on your computer in recent days that may have possibly caused a change in the behaviour in Vegas Pro 21?
Do you get normal results for one of the benchmarks in my signature?
As far as I'm aware VEGAS doesn't support the 10-bit 422 decoding the 5090 is capable of. Are you using such formats? I also think using two GPUs may not help or may cause issues (consider disabling one temporarily for testing purposes).
I'm having trouble with my current processor. My current processor is the best and fastest in the world. As you can see in the photo, Vegas is trying to render while my computer is completely asleep. What you mentioned doesn't matter. Vegas isn't using all the resources. Why?
@Mehmet-Src Vegas uses the resources it needs but there could be a bottleneck somewhere, like the media type or an Fx.
Feel free to try the benchmarks in my signature and I can say if the performance is worse than expected.
"My current processor is the best and fastest in the world"
But maybe not optimal for VP.
Very high cpu core count and so low ghz per core will result in lower rendering speed than say an 8 or 16 core cpu.
This may or may not change with vp23 if the multi thread count rendering is improved.

@Mehmet-Src I had the exact same problem with my PC, my specs are the same although slightly lower & an older version.
Google -
Does the AMD Ryzen Threadripper PRO 7995WX have integrated graphics?
No - the AMD Ryzen Threadripper PRO 7995WX does not have integrated graphics. As a high-end workstation-class processor, it is designed for heavy professional workloads and requires a dedicated graphics card to provide a display output.
It sounds like you did as I did, you bought the PC parts that were the biggest & had the most expecting Vegas to wizz along at lightening speed. Sorry it doesn't work like that.
You have a strong & stable PC that will multi task without issues but it's not fast. IE. I can render at the same time with more than one editor, work in programs such as a photo editor or CAD while that render is going on &! have YT playing a video on my other screen. I've tested this & then closed all the other apps & tried rendering again with just one editor - the render speed didn't improve, Like Google & I say - stable but not fast.
Vegas's compatibility with RTX5090? I'm not sure about that, that GPU has popped up in the comments a couple of times. 🤷♂️
Why does rendering continue intermittently
The intermittent rendering is just something Vegas does, there's no fix for it, hopefully the Vegas team will do something about that. If you want better rendering speed & usage of your GPU buy Voukoder, that's what I use.
This is rendering a 1.40min UHD clip. Magix HEVC vs Voukoder.
Why do video thumbnails disappear from the timeline?
If I edit & then play... my thumbnails don't update until I press pause, I'm assuming it's a Vegas thing 🤷♂️ It can be a little frustrating but I zoom out & the thumbnails refresh. 🤷♂️
----------------
Mt PC, motherboard & CPU has a server history, 'strong & stable' but not fast. I'm not sure whether this still applies to your version..
--------
PS. I've grown to appreciate my PC. It may not be fast but it is fast enough & It never crashes or overheats even though it's on for days.

PPS.
AMD Ryzen Threadripper PRO 7995WX 96-Cores 2.50 GHz
2.50GHz isn't fast.
256 GB Ram
I went with 256GB of RAM because at that time I was also using Adobe that uses RAM for prerendering, I no longer have Adobe but the large amount of RAM does come in useful with Vegas's Dynamic RAM Preview.
There was a down side to choosing that amount tho, my PC motherboard will accept up to 3200 MHz DDR4, but to get 256GB I had to downgrade to 2666MHz,
I don't know what speed your RAM is?
@Mehmet-Src While we really could use you to give the info we're asking for I have another idea.
Another user got advice from support for surprisingly slow NVIDIA 50XX performance here- does this also help you? https://www.vegascreativesoftware.info/us/forum/upgraded-gpu-from-nvidia-3070ti-to-nvidia-5080-now-vp22-slow-crashes--149151/?page=2#ca939717
@Mehmet-Src You're getting Avg 169,00 fps & the Current speed is 234,21fps. That seems pretty fast to me, I don't know what speed other people get,.
Depends what AR etc. your project is...
No need to disparage others' attempts to assist. Benchmarks can help understand what if anything is going on as there are many variables.
PugetSystems offers benchmarks for Resolve and Premiere I believe.
Guys, do you know what the only problem is? It's that our engineers at VEGAS don't care about this issue... Could you please add an update and settings menu for a computer with an AMD Threadripper 7995WX 96-core processor and dual GeForce 5090 graphics cards?
If the engineers didn't care, why would they be investing all this programming time into getting a new video engine off the ground? It is in "version 1" with improvements still coming.
As for adding/updating menu settings for your specific computer, you are an "outlier", a "unicorn" of sorts with computer builds, and I believe they have to work on getting the "masses" up and running first.
Feel free to try the benchmarks in my signature so we can compare and see if your computer is performing as expected.
In general those specs aren't optimal for VEGAS today. Lots of cores and multiple GPUs means computer power won't be utilized. I suppose that's a good thing if you are running other software at the same time you do video editing and can give it dedicated resources.
@Mehmet-Src As I wrote above. - Your PC although more cores than mine is similar in that the processor is a 'server/workstation processor', it's designed for stability & multifunctionality, not speed.
I was a little disappointed with Vegas's performance on my PC but I've come to appreciate that I can render UHD, watch/play YT & work in CAD or other programs all at the same time without a detrimental affect to render times &/or other programs usability etc.

@Mehmet-Src Vegas builds and versions later than vp21 b208 are optimized for a single gpu that does all video processing internally with minimal use of the pci bus. Earlier versions got better performance with separate gpus doing the rendering and decoding. But Vegas has no support for dual-gpu rendering with any brand of gpu. Intel Arc gpus have team rendering enabled in DaVinci but that approach has not been supported by Nvidia for years and the interface is absent in recent models like the 5090.
The Ryzen cpu you have is workstation/server grade with up to 128 pcie lanes but maybe not pcie5 preferred by the 5090. Cpu also has avx512 which I believe is supported by some DaVinci presets. Not sure what your pcie constraints are if populated with multiple x16 gpu boards. Best way to find out for sure is to do extensive benchmarking with your own typical projects and media comparing with 1 and 2 gpus plugged in as the number of m.2 drives increase. Also suggest you compare Nvenc rendering performance with cpu-only presets... curious if all that cpu power can outshine that of a 5090. If render quality is of importance to you, suggest you also measure that objectively with lossless media. See charts and links in my signature. Higher performance is often achieved at the expense of quality.
@Mehmet-Src Regarding the intermitted rendering, that was an issue with previous Vegas versions. I do not have the issue anymore with VP23 + RTX5090. Why are you still stuck on VP21? Surely not because you cannot afford an Vegas upgrade, as you are able to afford such expensive HW (as in 2x RTX 5090)...
Just out of technical curiosity, what kind of power supply do you have to feed 2x RTX5090's + the rest of your PC?
............ Why are you still stuck on VP21? Surely not because you cannot afford an Vegas upgrade, as you are able to afford such expensive HW (as in 2x RTX 5090)...
@bitman It wasn't the two RTX's that caught my eye, here in the UK - AMD Threadripper 7995WX 96-core processor - roughly £10k ! 😮
The minimum for an RTX5090 is 1000W PS, that is minimum, however,
a RTX 5090 has a 575W+ TDP and frequent, high transient spikes, making 1200W-1500W ideal for stability, efficiency, and headroom. So adding a second RTX 5090 adds at least 575W + TDP, and adding some margin, you need basically at least a 2000 W power supply. Good luck finding such one on regular retailers.
And especially in the US with their 120 V grid.
If I am not mistaken (and I could be, correct me if I am wrong), if you live in the US:
Standard US household outlets (110V-120V) are typically limited to 15 or 20 amps, providing a maximum continuous power of 1,440W (120V x12 A) therefore using a 2000W exceeds the safe, continuous load capacity of a standard circuit, posing a tripping risk.
Europe has 220-240V, so it is more feasible on standard power outlet plugs, but still, 2x RTX5090, that is a lot of power and heat...

@Gid the more reason to spend peanuts in comparison to the HW to upgrade to VP23...
@Mehmet-Src Reading through this thread I notice you've yet to tell us which build of VP21 you are using. Are you on build 315?
@Mehmet-Src a high core count is beneficial to rendering speed, however, there is also a point at where there is diminishing return on parallelism. The most optimal system is where a high core count and a high individual core speed and good distributed programming and resource management go hand in hand. However, processors with a high core count usually are clocked slower, which is OK as long as not to many cores are idling. Bad programming, latency, waiting on each other's result and resource holding like memory and disk access are enemies of parallelism.
And taking about Vegas, it may have hard boundaries of number of rendering threads, so have a lot of idling cores is not ideal, especially if the active cores are slow in comparison of CPU's which have fewer cores.
You should read up on it:
Parallel computing is often seen as the silver bullet for performance. The expectation is simple: if one core takes 100 seconds, then 4 cores should take 25 seconds (at least theoretically). But the real world is complex and messier. Sometimes adding more cores not only gives diminishing returns, it actually starts making things worse. This is known as Parallel Slowdown.
